Java

Dies ist ein informelles Treffen für Lernende, die ihre ersten Schritte in der Programmierung machen oder ihre Grundkenntnisse vertiefen möchten. *** This is an informal meetup, for learners that want to do their first steps in programming or want to consolidate their skills. We spend one hour and a half working on tutorials, exercises or projects. If you need help to get started, we will help you finding a good way for learning. You should be prepared to spend your time "doing things": just hanging around and listening might get boring, if all other people are learning on their side. There are experienced people are around and you can ask questions as soon as their arise or bring with you questions you have had during the week. During the last half an hour, we do a (simple) exercise together. We speak German, English, and a few other languages. Currently, how main programming languages are: * Python * Javascript * Java * Flutter * C++ * C * C# * PHP But you're free to learn any programming language during our Co-Learning! If you want to learn more about our Co-Learning, please have a look at our website (no frequent updates...): https://opentechschool-zurich.github.io/ If you're starting with Python, we can suggest: * Learning Python the hard way (https://learnpythonthehardway.org/python3/) (for Python 3). * The Solo Learn Python 3 Tutorial (https://www.sololearn.com/Course/Python/). * A big list of Python tutorials: https://docs.python-guide.org/intro/learning/ For Node.js: * Nodeschool: https://nodeschool.io/ For C++ * https://de.wikibooks.org/wiki/C%2B%2B-Programmierung * https://www.sololearn.com/Course/CPlusPlus/

Anybody who wants to practice their programming skills is welcome. We share our ideas, learn from each other, do some exercise, ask questions, etc. This meetup is the best for those who want to improve their skills by programming and learning in a group If you want to learn more about our Co-Learning, please have a look at our website: [https://opentechschool-zurich.github.io/](https://opentechschool-zurich.github.io/) \*\*\* We have a chat group you can join to get more information: [https://app.element.io/#/room/#ots-zh:matrix.org](https://app.element.io/#/room/#ots-zh:matrix.org) (You need to create a free account if you don't already have one) Remote participants are also welcome. You first need to join the Element chat and then get into the video call that we start at around 19:00 (if we forget, pleas ping us in the Element chat!) \*\*\* Our main languages are Python and Javascript, but we welcome every programming languages.

**Cloud Native Night Munich** AI agents are rapidly evolving from simple assistants into autonomous systems capable of reasoning, maintaining context, and interacting with complex environments. In this meetup, we’ll explore two practical applications of modern agentic AI in software engineering. The first talk dives into building stateful AI agents that work with real-time data, covering the architectural patterns and challenges behind creating responsive, context-aware systems. The second talk showcases how agentic AI can be applied to understanding and analysing complex legacy applications — helping uncover program flows, dependencies, and hidden system knowledge that would otherwise take countless hours to explore manually. Whether you’re building AI-powered applications, modernising enterprise systems, or simply curious about the future of intelligent software, this meetup offers hands-on insights into how AI agents are transforming the way we interact with technology THIS MEETUP WILL BE HYBRID. **\|** [Zoom Link](https://qaware-de.zoom.us/s/81669104769) \*\*\* AGENDA \*\*\* * 6\.30 PM \| Doors open\. Grab some snacks & drinks\. * 7\.00 PM \| Welcome & Intro – **Start of hybrid meetup** * 7\.15 PM \| **Building Stateful AI Agents with Real-Time Data**, Gregor Bauer (VP Customer Engineering at CrateDB) * \~8:15 PM \| **Hosty - The next level with Agentic AI,** Martin Binder (Lead IT Consultant at QAware) * afterwards: More snacks & drinks, and a lot of time for networking with all attendees and speakers. \*\*\* ABSTRACTS \*\*\* **Building Stateful AI Agents with Real-Time Data**, Gregor Bauer (VP Customer Engineering at CrateDB) Most AI demos are stateless. Real systems are not. Modern AI applications increasingly depend on continuously changing operational data: events, metrics, logs, transactions, sensor streams, and user activity. This creates a new architectural challenge: how do we build AI agents that can reason over live data while remaining scalable and observable ? This talk explores the architecture of stateful AI systems and agentic applications. We will cover: * streaming-first AI architectures * real-time context enrichment * combining vector search with structured queries * memory layers for AI agents * latency and scalability considerations * operational lessons from large-scale data platforms The session provides practical guidance for engineers designing production-ready AI platforms. **Hosty - The next level with Agentic AI,** Martin Binder (Lead IT Consultant at QAware) To migrate legacy systems, you need to understand these IT dinosaurs, at least partially. So code analysis up to a certain level is unavoidable. What used to take months, sometimes years without LLMs is now doable in a few days with Gemini and friends. And yet: you still have to drive the analysis yourself, stitch the LLM's partial results into a coherent picture and fight the context window. With old source files thousands of lines long, that part really hurt. Agentic AIs like Claude Code are not just another AI feature. They change how you approach unfamiliar systems — fast, and without the headaches that LLM chat workflows used to come with. Teaser: an analysis that took us a few days under "yay!" cheers is now done in minutes. \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* Please comply with our [Code of Conduct](https://www.greenmanifesto.de/en/code-of-conduct).

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

Elide is like Bun for Java and Kotlin: an all-in-one native toolchain, with drop in support for Java Kotlin. Drop in, with up to 20x faster compiles, and 100x faster code formatting. Elide leverages GraalVM for a new development modality: native-first tooling with fast startup and shutdown. Install Maven dependencies, format and compile Java and Kotlin, assemble Docker containers and JARs, all in one binary, and all in the time it takes Gradle to get its boots on in the morning. **Note**: This is a hybrid in-person/online event. Food and social for those in the OCI training room starts at 6:00pm. Presentation starts at 6:30pm for those online and in the training room.

Come join us for lunch together at Bendi Wok, one of my favorites!
